System Effectiveness Factors.[Part 2 : System Design & Development]
Reliability.Reliability with respect to systems and equipment is definedas the probability that a system will perform its intendedfunction for a specified interval under stated conditions.Three elements of reliability.
1. A probability of an item functioning as intended.2. An operational interval defined in time units or cycles.3. A definition of the item's operating environment.
System Effectiveness Factors.[Part 2 : System Design & Development]
Maintainability.Maintainability is the measure of the ability of a system tobe restored to a specified level of operational readinesswithin defined internals with the use of prescribedpersonnel, facility, and equipment resources. Two elementsof maintainability.
Corrective maintenance. The unscheduled actions, initiated as aresult of failure, that are necessary to restore a system to itsrequired level of performance.
Preventive maintenance. The scheduled actions necessary toretain a system at a specified level of performance.
System Effectiveness Factors.[Part 2 : System Design & Development]
Availability.Maintainability and reliability determine the availability ofsystems and equipment.
A measure of the degree to which an item is in theoperable and committable state at the start of a mission,when the mission is called for at an unknown(random) time.
Availability is thus defined as the probability that an itemwill be available when required or as the proportion of totaltime that an item is available for use.
System Effectiveness Factors.[Part 2 : System Design & Development]
Supportability.Supportability means to the degree to which a system canbe effectively supported, both in terms of the built-in designcharacteristics of the overall maintenance and supportinfrastructure.
It relates to levels of maintenance such as :- Organizational Level.- Intermediate Level.- Depot Level.

Manufacturing Strategy[Part 3 : Acquisition & production Support]
Assemble-to-Order.
A production environment where a good or service can beassembled finally after receipt of a customer's order.
Manufacturing Strategy[Part 3 : Acquisition & production Support]
Make-to-Order.
A manufacturing process strategy where the trigger to beginmanufacture of a product is an actual customer order orrelease, rather than a market forecast.
Manufacturing Strategy[Part 3 : Acquisition & production Support]
Engineer-to-Order.
A process in which the manufacturing organization must firstprepare (engineer) significant product or processdocumentation before manufacture may begin.
Manufacturing Process.[Part 3 : Acquisition & production Support]
Product Layout (Flow Shop).
- A limited range of similar products is produced.- Workstations are dedicated to specific operation.- Demand must be sufficient to justify setting up the process.- It is capital-intensive.- Little buildup of work-in-process inventory.- Short throughput and manufacturing lead times.- Generally lower unit cost.
Manufacturing Process.[Part 3 : Acquisition & production Support]
Process Layout (Job Shop).
- Lots or batches are produced intermittently.- General-purpose machinery is used.- Departments are based on similar types of skills and equipment.- Work moves only to those stations required and skips the rest.- Product or volume can be changed relatively easily.- Production and inventory control are complex and expensive.- Work-in-process inventory levels are high.- Lead times are longer.
Manufacturing Process.[Part 3 : Acquisition & production Support]
Cellular Manufacturing.
U-Shaped CellC-Shaped Cell
- A cell is a manufacturing unit consisting of a number of workstations plusthe material transport mechanism and storage buffers that interconnect thecells.
- This manufacturing process produces families of parts within a single lineor cell of machines operated by machines who work only within the lineor cell.
Demand Forecasting.[Part 3 : Acquisition & production Support]
Demand Forecasting.
A forecast can be determined by mathematical means usinghistorical data, it can be created subjectively by usingestimates from informal sources, or it can represent acombination of both techniques.
Make or Buy Analysis[Part 3 : Acquisition & production Support]
Make or Buy Analysis : Some Consideration.
Making Buying
- Cost considerations(less expensive to make the part).
- Desire to integrate plant operations.- Productive use of excess plant
capacity to help absorb fixed overhead.- Need to exert direct control over
production and/or quality.- Design secrecy required.- Unreliable suppliers.- Desire to maintain a stable work force
(in periods of declining sales).
- Supplier's research and specializedknow-how.
- Cost considerations(less expensive to buy the part).
- Small-volume requirements.- Limited production facilities.- Desire to maintain a stable work force
(in periods of rising sales).- Desire to maintain a multiple-source policy.- Indirect managerial control considerations.- Procurement and inventory considerations.

Contracting.[Part 3 : Acquisition & production Support]
Fixed Price Contracts.- Fixed price contracts are based on a price that will not
differ from that agreed upon or understood to apply atthe time of ordering.
- As contract terms lengthen or as complexity of developmentor performance increases, supplier risk rises in fixed pricecontracts.
Common fixed price contract types.1. Firm Fixed Price.2. Fixed Price with Adjustment/Escalation.3. Fixed Price with Redetermination.4. Fixed Price with Incentive.
Contracting.[Part 3 : Acquisition & production Support]
Cost Reimbursable Contracts.- Cost reimbursable contracts guarantee the supplier a
price sufficient to cover allowable costs plus whatever
additional amount is negotiated.
- Because financial risk falls on the purchaser, thepurchaser must carefully monitor such contracts.
- Types of Cost Reimbursable Contracts.1. Cost Plus a Fixed Fee.2. Cost Plus Percentage of Cost.3. Cost Plus an Incentive Fee.4. Cost Without Fee.5. Cost Sharing.

Logistics Management.[Part 4 : Distribution & Customer Support.]
Logistics Management.Logistics management is that part of the supply chainprocess that plans, implements and controls the efficient,effective flow and storage of goods, services and relatedinformation from the point-of-origin to thepoint-of-consumption in order to meet customer'srequirements.

Douglas M. Lambert, James R. Stock, Lisa M Ellram, "Fundamentals of Logistics Management," McGraw-Hill, 1998. p5.
Elements of Logistics Management.[Part 4 : Distribution & Customer Support.]
Transportation.Transportation is a very important part of the logisticssystem. A major focus in logistics is upon the physicalmovement or flow of goods or upon the network thatmoves the product.
This network is composed of transportation agencies thatprovide the service for the firm. The logistics manager isresponsible for selecting the mode or modes oftransportation used in moving the raw materials andfinished goods or for developing private transportation asan alternative.
Elements of Logistics Management.[Part 4 : Distribution & Customer Support.]
Storage.A second area, which has a trade-off relationship withtransportation, is storage. It involves two separate butclosely related activities : Inventory management andwarehousing.
A direct relationship exists between transportation and thelevel of inventory and number of warehouses required. Forexample, if firms use a relatively slow means oftransport, they usually have to keep higher inventory levelsand usually have more warehousing space for thisinventory.
Elements of Logistics Management.[Part 4 : Distribution & Customer Support.]
Packaging.A third area of interested to logistics is industrial (exterior)packaging. The type of transportation selected affectspackaging requirements both for moving the finishedproduct to the market and for the inbound materials.
For example, rail or water transportation usually requiresadditional packaging expenditures because of the greaterpossibility of damage.
Elements of Logistics Management.[Part 4 : Distribution & Customer Support.]
Material Handling.A fourth area to be considered is materials handling, whichis also of interest to other area in the typical manufacturingorganization.
Material handling is important to efficient warehouseoperation. Logistics managers are concerned with themovement of goods into a warehouse, the placement ofgoods in a warehouse, and the movement of goods fromstorage to order-picking areas and eventually to dock areasfor transportation out of the warehouse.
Elements of Logistics Management.[Part 4 : Distribution & Customer Support.]
Order Processing.Order processing may require shorter delivery lead time,and the short delivery lead time may require a premiummeans of transportation. If order processing is consideredpart of the logistics, then the company might examineimprovements, such as telephone calls and more computerequipment for processing, to reduce order processing time.This would allow the firm to use much cheapertransportation and still get the goods to thecustomer with required days.
Transportation.[Part 4 : Distribution & Customer Support.]
Legal Forms of Transportation.Common Carriers.
Carriers in this legal classification are available to all users atpublished rates. All tariffs are approved by the cognizant regulatoryagencies.
Contract Carriers.Carriers in this legal classification perform selected transportationfunction. Rate differentials for the same type of service are allowed;however, these rates must be published and made a matter of publicrecord.
Transportation.[Part 4 : Distribution & Customer Support.]
Legal Forms of Transportation (cont).Exempt Carriers.
Transportation companies in this classification primarily moveunprocessed products, such as agricultural products and fish. Exemptcarriers are exempt from economic restrictions by regulatory bodies.
Private Carriers.Carriers in this legal classification are operated by the producer ordistributor of the cargo. A private carrier is not legally for hire byoutside organizations.
Transportation.[Part 4 : Distribution & Customer Support.]
Advantages of Individual Modes.Rail.
- Mass movement of goods. - large capabilities.- Low unit cost of movement.- Dependable form of transport.- Long-haul movements.- Fairly extensive rail system network - coverage to major markets
and suppliers.- Numerous ancillary service - switching, in-transit privileges,
storage, etc.- Goods transfer to other carriers.- Specialized equipment.
Transportation.[Part 4 : Distribution & Customer Support.]
Advantages of Individual Modes (cont).Highway.
- Flexibility - can go anywhere.- Speed - 3 - 5 days delivery to any point in continental Untied
States.- Frequency - hourly and daily pickup and delivery service.- Convenience - loading and unloading at the shipper's and
receiver's places of business.- Goods transfer to other carriers.- Equipment diversity.
Transportation.[Part 4 : Distribution & Customer Support.]
Advantages of Individual Modes (cont).Water.
- Mass movement of bulk commodities - large capabilities.- Very low unit cost.- Movement of low-unit-value commodities, such as sand, gravel,
or shell, which otherwise would have limited distribution.- Long-haul movements.
Pipeline.- Mass movement of liquid or gas products.- Lowest unit cost of movement.- Large capacity and volume of throughput.- Most dependability of all the modes.- Long-haul movements.
Transportation.[Part 4 : Distribution & Customer Support.]
Intermodal Transportation.Truck-rail (Piggyback). Truck-rail service may be
trailer-on-flatcar(TOFC) or container-on-flatcar(COFC).
Truck-water(Fishyback). This combination involves intermodal truck
and water service, sometimes referred to as "fishyback," which isaccomplished by coordination of truck and water transport movements.
Air-truck. It provides feeder and delivery service between major
airport hubs and remote communities deprived of adequate air freightservice.
Rail-water. The "hydro-train" rail-water service.
Transportation.[Part 4 : Distribution & Customer Support.]
Transportation Rates.Class rates. The following factors are used in determining freight
classification : (1) density, (2) stowability, (3) ease of handling goods,(4) liability - value per pound, fragility, theft risk, flammability,explosiveness, environmental impact, perishability.
Exception Rates. Exception rates, or exceptions to the classification,
provide the shipper with rates lower than the published class rates.
Commodity Rates. Commodity rates apply when a large quantity of
a product is shipped between two locations on a regular basis.
Contract Rates. Contract rates are those negotiated between a
shipper and carrier.

Warehousing.[Part 4 : Distribution & Customer Support.]
Material Handling Systems.Storage and order picking equipment includes racks, shelving,drawers, and operator controlled devices such as forklift trucks.
Transportation and sorting. The order picker can use a largeselection of powered and non powered equipment for transporting andsorting items located in the racks, shelves, and drawers. Examples ofapparatus of this type include forklift trucks, platform trucks, handtrucks, cranes, and carts. This equipment performs multiple functions inaddition to transportation and sorting, such as order picking.
Shipping. Shipping of products to customers involves preparing itemsfor shipment and loading them onto transportation carriers. Equipmentsuch as pallets, palletizers, strapping machines, and stretch wrappersare important.
